How To Choose Sunglasses?

Wearing sunglasses is essential to protect your eyes from the harmful effects of the Sun. They are not just useful in summer, but also throughout the year. Opticians Vision Plus accompany you and help you to effectively make your choice.

To choose her glasses several elements be taken into account:

Indices

Initially, to determine what will be the main use of the mount: each type of activity has a light intensity. This choice defined index that corresponds to your needs and determines a color of glass (ranging from light to dark) and a protection rate. The index, the more it reduces the light intensity.

So the glasses with one index 0, very clear or slightly tinted, are recommended for use in the city. As for glasses with index 4, very dark, they are perfectly suitable for conditions very sunny as the sea or the mountain.

The marking “This” is essential, it guarantees the presence of a protection on the glasses. The words ‘UV 400’ or ‘100% UV’ tells you that the glasses filter out UV, offering optimum protection.

 

The shape of the glasses

For added protection, choose covering glasses, they protect both the underside and the top of the eyes.

To mitigate the reflections on reflective surfaces or to improve contrast and visual perception, use polarized lenses.

Sunglasses, for whom?

Sunglasses are recommended for everyone and all ages !

However, children under 12 years old are very sensitive to ultraviolet rays because their crystalline do not filter them completely. It is essential to protect them from a young age, especially if they have clear eyes.

Attention:

The index is not a protection ! Indexes allow you to adjust the hue of your glasses to light intensity depending on the situation. The index is high, the glass is dark and so more glare will be low. Only lenses against ultraviolet treatments protect you!

    Wear sunglasses without filter UV is much more harmful than to not wearing! Those are the filters on lenses that will protect from UVA and UVB RAYS, without them, the pupil dilates so letting ultraviolet.

    Category 4 is not suitable for the uses of the road!
